I apologize if my formatting of this question is poor as this is my first time submitting a question here but I will do my best to include all possible information. I am using Arduino IDE version 2.3.2, SparkFun Apollo3 Boards version 2.2.1, and MCP4725 version 0.4.0.
Below is the output messages from compiling my code.

Using library Wire at version 2.0.0 in folder: C:\Users\sbrink\AppData\Local\Arduino15\packages\SparkFun\hardware\apollo3\2.2.1\libraries\Wire Using library MCP4725 at version 0.4.0 in folder: C:\Users\sbrink\Documents\Arduino\libraries\MCP4725 exit status 1
Compilation error: exit status 1
I am uncertain if I need to include the code files I am trying to compile as it appears to me that these are library compatibility issues; however, if it is necessary to debug the problem, let me know and I will include them.
Previously library compatibility issues existed between the MCP4725.h/MCP4725.cpp and ArduinoSDK.h files. This was due to multiple definitions of PDM between the files. So I commented out the experimental function writePowerDownMode in the MCP4725 files as it was responsible for the multiple definitions and I am not going to be using the function.
Then after recompiling I receieved the above error messages stating "fatal error: cstddef: No such file or directory."
I searched in the apollo3 cores and found <mstd_cstddef> so I tried including that instead of in the platform.h file. Then the complier told me that , , and caused fatal directories and could not be found, so I switched to "stdlib.h", "stdio.h", "string.h" and then received these errors:

which seemed to be leading me down the wrong path so I reverted back to the original code in platform.h and have since found myself here on stackoverflow asking for your assistance.
